'WINDMILL.

SPECIFICATION forming part of Letters Patent No. 351,537, datedOctober26, 1886.

Application filed March 26, 1886.

. To all whom, it may concern.-

t be expanded to throw the floats into the wind,

or such arms may be thrown back in a line substantially parallel withthe crank shaft, thereby throwing the floats backward and causing themto present their edges to the wind.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a rear view of the windmill, one of the floats and itssupporting-arm being removed to disclose the construction of the mainsupporting-pivot. Fig. 2 is a side view of the mill, the pivot and itssupporting-plate being shown in central vertical section, and the hubcarrying the float-arms being also shown in central vertical section.

The windmill forming the subject-matter of this application could bemounted on any form of tower or mast desired; but it is preferablymounted on a mast made of cast or wrought pipe set in a verticalposition and properly guyed, as indicated in Fig. 1, wherein Arepresents the mast. .To the upper end of the'mast Athere is secured aplate, B, formed with a central aperture and with a downwardly-extendingplate, b, at the bottom of which there are arranged outwardly-projectinghorizontal arms a a. The main pivot O of the mill is fitted within theaperture formed in the plate B, and guided at its lowerv end by the armsa a, being held in position by a strap, a, that is held to the arms aaby set-screws, the lower end of the pivot 0 being formed with an annulargroove, (1, in which the arms a a and the strap c'are fitted. The pivotG carries a plate, D, that is provided with vertical standin thesestandards there are I allowed to drop to the position shownin dottedards e e, and

formed bearings which support and hold the crank-shaft E. Upon theextending end of the crank-shaft E there is a hub, F, formed with radialarms f, as many of such arms being provided as there are to be floats inthe mill. The floats G G are rigidly secured to their supporting-arms Hin any manner desired, but preferably by means of loops andsetscrews, asindicated in the drawings. The arms H are each provided with auxiliaryor bracing arms h, and the inner ends of the main arms H and of theauxiliary arms h are apertured, so that they may be fitted upon thearmsf ol" the hub F, being held to place upon said arms by pins 13, orby nuts or any other convenient device which will prevent thedisplacement of the arms.

A sliding collar, I, is mounted on the shaft E,

between the hub F and the outer standard, 6, and this collar 1 isprovided with as many pinsj as there are armsf on the hub F, and each ofthese pins j is connected with one of the arms H by a connecting-linlgasZ, said links being pivotally connected to the arms H, and looselymounted on the pins j. To the side of the plate D opposite to that fromwhich the shaft E projects there is secured a bracket, K, and to thisbracket K there'is pivotally connected a lever, N, to the end of whichthere is secured a weight, N. This lever N is connected to the collar Ibymeans of a bifurcated connectinglink, L, the forked end of whichstraddles the collar, so thatthe pins or pr0- jections 0, carriedby saidforked end, may enter a groove formed in the collar. The short arm ofthe lever N is formed with an Lshaped projection, n, and to thisL-shaped projection -12 there is secured a wire, 19, the lower end ofwhich-is fixed to a yoke, q, encirclinga collar, P, within which themain connecting-rod R slides. This collar P is engaged by a forkedprojection, 1', which extends from a sliding plate, T, that is securedto the mast, and this plate T is in turn provided with adownwardlyextending wire, t, which is secured to a cleat near theground. The crank-shaft E is connected to the rod R by means of thepitman or connecting-rod S, and a swivel-joint, V, is arranged in theshaft R, as indicated.

When it is desired to throw the mill into operation, the wire t isreleased and the lever N- lines in Fig. 2, and this movement of thelever will carry the float-arms forward, so that they will extend atabout right angles from the axis of the crank-shaft, thus bringing thefloats into a position to be operated upon by the wind, it being ofcourse understood that the floats are set at an angle to the crankshaft.

When it is desired to throw the mill out of use, the lever N is drawn tothe position shown in full lines in Fig. 2, which movement of the leverwill throw the collar-I up close to the hub F and cause the arms H toswing upon their connection with the arms f until they extend to therear of the shaft E in lines that are about parallel with the axis ofsaid shalt.

The many advantages of such a mill as I have described are so perfectlyapparent that it is needless for me to go into any extended enumerationof such advantages.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a windmill, the combination, with a crank-shaft, of a hub carryingradial arms, floats rigidly secured to arms that are pivotally connectedto said radial arms, a sliding collar carrying pins, connecting-linksextending from said pins to the float-arms, a lever,

and a link extending from said lever to the pin-carrying sliding collar,substantially as 30 described.

2. The combination, with a crank-shaft, of a hub carrying radial arms,floats that are rigidly secured to arms that are pivotally connected tothe said radial arms, a sliding 001- 5 lar mounted onthe crank-shaft andcarrying pins, connecting-links Z, extending from said pins to thefloat-arms, a weighted lever, N, a link, L, connecting the lever and thesliding collar,and an operating mechanism consisting. o essentially, ofa wire extending to the ground and having an interposedswivel-connection.

3. The combination, with the turn-table ofa windmill and a shaft mountedthereon, of a hub mounted rigidly on the shaft and pro- 5 vided withradial arms, float-arms pivotally mounted on said radial arms, a slidingcollar on said shaft, connections between said collar and thefloat-arms, and a weighted lever mounted on said turn-table and havingits shorter 0 end connected with the sliding collar, substantially asshown and described.
